PROTAC FGFR2 degrader 1

PROTAC FGFR2 degrader 1 (compound N5) is a PROTAC that effectively targets FGFR2 with DC50 of 6.46 nM, the FGFR2 IC50 is 0.08 nM. PROTAC FGFR2 degrader 1 has anti-proliferative activity and highly selective, induces G0/G1 arrest of KATOIII and SNU16 cell cycle and inhibits apoptosis by reducing the activation of p-ERK and p-PLCγ, the downstream proteins of FGFR2. PROTAC FGFR2 degrader 1 inhibits gastric cancer cells remained above 50% at a concentration of 0.17 nM. PROTAC FGFR2 degrader 1 potently inhibits the growth of SNU16 xenograft tumors in mouse model (Structure Note: Pink, FGFR2 activator: HY-18708; Blue, E3 ligase ligand: HY--10984; Black, linker: HY-163989; E3 ligase ligand + linker: HY-163986) [1].
